It would be nice to see the series gaps plugged for the Xbox and PC users, which honestly doesn't seem that unreasonable. As a series fan on the Sony side, it's great seeing new fans come to the franchise, and I want them to have that full-experience too.
I suspect some of that is down to a case of pacing those releases for a new audience, because the schedule since Zero made the breakthrough has been pretty wild.
Also, more 'Ryu Ga Gotaku Studio' stickers in the game boxes please; it's a nice touch!
